That would be quite true.

I found that 365km trips between Dunedin & Christchurch were far less
fatiguing when done in the wee hours (only a few trucks on throad at
that time of day) at @160 in my 74 Passat and diesel Skyline. Both
cars were quite happy to sit on that speed, though that was also the
Nissan's top speed.

Unfortunately there are more cops now, and more peolpe have
discovered the ease of driving at that time, so now you can't even
use high beam...
